Vernon - He is a guy who has purposedly and meticulosly reduced his life and worldview to the bare essentials as he scared of having the good things in his life taken from him and then made miserable... He would be happy never having someone try and kill him, yet again!
Azreth - A lover at heart, his biggest dream is to chill and live a laid back life with the people he loves... He does have a sizeable ego, so his 'perfect wordl' would not nescessarily be the perfect world for the people he loves..
Grey - Though one might think his dream is actually having his clan and family back, Grey's dream is actually a lot more simple... He often feels dejected at his own life, he no longer finds joy at anything anymore and has become apathetic to life itself, Vernon and Azreth change that a bit, but can't fully fix that... His biggest dream would be to feel conected like he used to as a child, to feel like he belongs and to feel what he identifies as 'love' again... In short, he wants to get rid of his emotional impostor syndrome.
And though these are the characters dreams, they only account for 'right now' in the story,
As Vernon learns how to assert himself he becomes bolder and more willing to have a dreams and aspirations of a true hero.
Azreth learns how to manage his ego. so he has to reasses what is it he trully wants
Grey learns how to open his feelings again, and finds his dream wasn't as far as he originally thought
And of course, when they change, so too do their dreams and aspirations... JTA is meant to be a long story, so these changes have been signaled to be happening slowly, and will evolve over time changing into new and grander goals as the story grows in scope. ^^
